文章对冷表面上水滴沉积结冰和撞击结冰微物理过程的实验研究进展进行总结。提出影响水滴结冰的因素主要有冷表面、环境条件、水滴自身和附加力/场,重点介绍了低能表面抑冰性能和对流情况对水滴结冰影响的研究现状。最后,指出不同因素对水滴结冰的影响规律,超疏水表面抑冰性能的优化,以及结冰过程主动控制方法的探索可以开展深入研究,为进一步研究和应用提供参考。

The present review summarizes the experimental investigations on the freezing processes of the sessile water droplets and impinged water droplets on cold surfaces. Cold surfaces,environmental conditions,droplets,and additional forces or fields are presented as the dominant factors that influence water droplets freezing. The anti-icing performance of low-energy surface and effects of convection conditions on the water droplets icing processes are highlighted. Finally,the principles of various factors on the water droplets freezing,optimization of super-hydrophobic surface anti-icing performance,and exploration of active control methods on freezing process are recommended to be investigated further,which can be a reference for future researches.
